Hardware random number generator on USB
This is one cool source of true randomness.
Device featuring a real sand timer, servo rotating mechanism, optical beam for detecting randomness of sand particles falling through (but not sand droppings) is a really cool device for generating random numbers. Anyway, I will not get into the discussion of how random results of this random generator are, just watch the video after the break and check out the results at the project page (the source) link below the video.
